​Iron core inductors are vital components in electronic circuits, with their behavior influenced by various factors, including frequency. Examining the influence of frequency on the behavior of iron core inductors is essential for understanding their performance in different applications and frequency ranges.

The skeleton of the I-inductor is supported by the winding of the copper coil. I-inductance is one of the attributes of an electronic circuit or device.

1) The same type of components can be replaced from the scrap circuit board. 2) First determine the inductance and current value, replace it with an ordinary inductor with a pin, and fix it well.

From the appearance, such as a square or round inductor with a magnetic core, slightly larger volume, can see the core and coil.
